' MEANS FOR SECURING GLASS PANES INIPOSITIC To all whom it may concern:

Be it known that 1, JOHN KNonRL, a citizen of the United States, and residing at (lovington, Kenton county, State of Kentucky, have invented certain new and useful Means for Securing Glass Panes in Position; and I do declare the following to be a clear, full, and exact description of the invention, attention bein called to the accompanying drawing, wit 1 the reference characters marked thereon, which forms also a part of this specification.

This invention relates to certain new and useful means for holdii'ig a sheet or pane of glass in position within a frame arranged around its edges and adapted to receive it. Practical application of the invention is found by use in connection with sash-frames or" windows and similar and related appurtcnances used in building-constructions.

In the following specification and particularly pointed out in the claim at the end. thereof, will be found a full description of my invention, together with its parts and COnS 'jLCtiOI1, which latter is also illustrated in the accompanying drawing, in which:-

Figure 1, shows in perspective view a window-sash ofcustomary form and cons ruction and provided with. my improved means for holding the pane of glass in position which is used to fill it. Fig. 2, in a similar View illustrates manner of inserting the glass. Fig. 3, is a top-view of the sash. Fig. 4:, is an enlarged vertical section of it, parts intermediate its height being broken out. Fig. 5, is a part of a horizontal section near one side of the sash. Fig. 6, shows in per spective view and at enlarged. scale a part near one of its ends, of a certain member used in my invention.

The drawing shows my invention applied to a sash forming part of, or constituting a window.

A, is the a per sash-rail, B is the lower rail and CO are the two side-rails.

The rails at their ends where they come together are connected to each other by joints, more or less permanent. and made according to customary methods and usages of carpentry. Excepted however is the connection at the ends of one of the rails where it is not permanent, that is to say said rail may be readily detached at any time. When in position however, its connection is such that it firmly occupies its place and forms Specification of Letters Patent.

with the other rails a rigid sash-fraine' The:

top-rail A is thus connected, a mortis'e'imd tcnouqoint being used, the joined parts ing held together byclosely. fitting dowel; pins 1). 3'

7---7 are the mortises at the up er end of each of the upright rails C, C, {UK 8 are the tenons, one at each end of the upper rail A and fitted to occupy the mortises.

Pcrforations (Z are provided in the "en gaged, overlapping parts of the rails, where they come together, to which the dowel-pins I) are fitted. In a wooden saslnframe, tiese dowcl-pins are preferably of hard wood, to

prevent swelling, and they are closely fitted to retain their position without any other holding means.

The rails on their inner'side arefallgroove for reception of the edges of'the glass-panel E, there being a groove a in rail A, a groove 7) in rail B, and grooves 0 0 in rails G, C. The parallel, opposite sides of the grooves are of even depth and the grooves are so 100. ed in the particular side of the rails, that when these latter are connected, they come together at the corners whereby a continuous groove of even depth results which extends all around the four sides of the frame .on the inside thereof. A sheet of glass may therefore be inserted as illustrated in Fig 2. The frame as shown there, consists of the rail B and rails C, G permanently connected to it, and is open at one side from which the glass, cut to proper size, is passed in between grooves 0 c of the opposite, parallel rails C C. After seated in groove b, of rail B the remaining rail A is placed in )osition and secured by pins D, as shown in 1. All parts beiiw properly fitted and the glass cut to the rigdit height, its upper edge will be received by groove a of thls rail A, as soon as this latter 15 in position, as shown in Fig.4.

The grooves in the rails BC-C exceed 7 in width the thickness of the glass, the excess being occupied by ll0ldl.;g strips F, there bein one for e'ach of these three grooves an of proper length to entirely fill them between their ends. As to the other dimensions, they are such that they snugly till the rooves in depth and in width, less the thic mess of the glass and without projecting above the grooves so that the intact appearance of the sash-rail is restored without making the presence of these strips noticeable. Proper holding fit is obtained by having one of the sides of the strips slightly tapering, as shown at f, so that, after pressed into the grooves,-they become wedge-seated 5 and frictionally engaged which, consideringv their position, is sufiicient to cause them to remain in place in case shrinkage should reduce their hold. In such case, even if shrunk, the strips would nevertheless remain in position, being sufliciently confined by the sides of the grooves which support them. The connectlon in this manner of a glassanel to its frame is clean and quick and of neat appearance after finished, and preferable to a putty-joint.

In case breakage makes re lacing of a panel necessary, the detachab y connected rail is removed as shown in Fig. 2, strips F are pulled out and re-seated after the new panel is in place.

To facilitate quick work, shoulders 9 are formed near the upper ends of rails C C, and on their inner sides upon and a ainst which rail A comes to a dead stop. penings d which receive thQ'LdOWBl-PHIS D are e; so bored with reference to these shoulders, that when rail A has come to its seat on them, these openings register with each other end and alining holes therethrough,

so that no difliculty or delay arises when the pins are to be inserted.- These shoulders are produced by removing some of the material of each rail on one side of mortise 7. I

10 are recesses provided to receive the sash-cords and to permit connection to the sash. v

Having described myinvention, I claim as new:

A window sash comprising a base rail, stiles rigidly connected thereto, said rail and stiles having longitudinal grooves on their inner surfaces, an up er detachable rail having a groove therein, clamp a light of glass in'said groove, said upper rail having a double .tenon at eitheg sa-i stiles havin a mortise and having a hole therethrou holes of the stiles and rails, and a dowel r'zn adapted to extend into said holes.

In testimon whereof, I hereunto afiix my signature in t e presence of two witnesses. JOHN KNOERL. Witnesses:
